This prospective study aims to examine the association of specific genetic variants (single nucleotide polymorphisms) located on chromosome 1, 4 and 16, with presence of non-pulmonary vein triggers (NPVT) as well as ablation-outcome in AF patients
Description: Isolation of pulmonary-vein antra and all extra-pulmonary vein triggers
Measure: PVAI and isolation of all non-PV triggers Time: 1 hour of the ablation procedureDescription: Recurrence will be defined as freedom from atrial flutter (AFL), AF or atrial tachycardia (AT) of > 30 seconds duration, in the absence of anti-arrhythmic drugs (AADs) at follow-up.
Measure: Recurrence of arrhythmia Time: Within 1 year of follow-upCohort
There are 6 SNPs
